W5: The Soul Nebula
Image Credit & Copyright: Jeffrey Horne
Explanation: Stars are forming in the Soul of the Queen of Aethopia. More specifically, a large star forming region called the Soul Nebula can be found in the direction of the constellation Cassiopeia, whom Greek mythology credits as the vain wife of a King who long ago ruled lands surrounding the upper Nile river. Also known as Westerhout 5 (W5), the Soul Nebula houses several open clusters of stars, ridges and pillars darkened by cosmic dust, and huge evacuated bubbles formed by the winds of young massive stars. Located about 6,500 light years away, the Soul Nebula spans about 100 light years and is usually imaged next to its celestial neighbor the Heart Nebula (IC 1805). The featured image, taken from near Nashville, Tennessee, USA, is a composite of 234 hours of exposures made in different colors: red as emitted by hydrogen gas, yellow as emitted by sulfur, and blue as emitted by oxygen.

说明: 恒星正在埃塞俄比亚女王的灵魂星云中形成。更具体地说，在仙后座方向，可以找到一个名为灵魂星云的大型恒星形成区。根据希腊神话，仙后座是一位国王的虚荣妻子，这位国王曾统治尼罗河上游周围的土地。灵魂星云也被称为Westerhout 5（W5），其中包含几个星团、被宇宙尘埃遮蔽的脊状结构和柱状结构，以及由年轻大质量恒星的风形成的巨大空泡。灵魂星云距离地球约6,500光年，跨度约100光年，通常与它的天体邻居——心脏星云（IC 1805）一起成像。这张主题影像拍摄于美国田纳西州纳什维尔附近，是由234小时曝光的不同颜色照片合成的：红色代表氢气发出的颜色，黄色代表硫发出的颜色，蓝色代表氧发出的颜色。
